This invention relates to new and useful improvements in a reservoirbrush.

More speciiically, the invention proposes the construction of areservoir brush characterized by the provision of a hollow body having abottom perforated wall and another wall formed with an opening throughwhich a iiuid may be supplied to the interior of said body so as to becapable of passing through said perforations for saturating the bristlesmounted upon the outer face of said bottom wall and between saidperforations.

Still further the invention proposes the provsion of a perforatedshutter slidably mounted within said body for covering the perforationsin said bottom wall and movable in a manner to align its perforationswith the perforations Vof said bottom wall for permitting the liquid topass therethrough inthe aligned position and for limiting the liquidfrom passing therethrough in a ydisaligned position.

The invention has for another object the asso .ciation of a member withthe shutter for blocking off certain of said perforations when desiredand movable to .an inoperative position when desired.

.Still further the invention contemplates an .arrangement whereby themember mentioned in the previous paragraph may be moved by meanscontrolled eXteriorl-y of the reservoir brush.

A novel arrangement is also proposed for opening up said reservoir brushand making said :shutter and said member accessible.

Another object of this invention is the provision of a novel means formoving said shutter from the outside in said body for causing the:aligning and disaligning of said perforations for controlling thepassage of liquid therethrough.

For further comprehension of the invention, and of the objects andadvantages thereof, referkence will be had to the following descriptionand accompanying drawing, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

Fig. '7 is a vertical sectional view taken on the line 'l-T of Fig. 6.

The reservoir brush, according to this invention, includes a hollow bodyl0 of cylindrical form having al bottom wall I l and a top wall I2, Thetop wall I2 is maintained in position by means of a plurality of screwsI3 and is formed with an opening l2@L through which a liquid may besupplied to the interior of the hollow body I0. The 'bottom wall Il islikewise held in position by means of a plurality of screws I4 and isprovided with a plurality of perforations IIa which extend therethroughand connect the interior of said body with the bottom of the bottom wallIl. A plurality ofy bristles I5 is mounted upon the bottom face of thebottom wall il and between the perforations I Ia and the liquid passingfrom the hollow body is adapted to saturate the bristles. f

Means is provided for closing the `opening I2a and consists o f a coverI6 having a depending skirt portion I5a which is adapted to be engagedinto the opening I25L for holding the cover in position thereon. Thecover I6 is provided with a handle I1 which is adapted to be manuallygrasped and pulled for removing the cover I6 from the top wall I2.

A perforated shutter I8 is mounted within the hollow body I0 and -uponthe inner face of the bottom wall II. The shutter I8 is formed with aplurality of perforations I8a which are adapted to be aligned anddisaligned with the perforations I Ia for controlling the passage offluid from the hollow body Il). The shutter I8 is adjustably supportedupon the inner face of the bottom wall II `by means of a plurality ofpins I9 which extend from the inner face of the bottom wall Il and whichpass through elongated slots 2B formed in the shutter I8. The slots 20are of Vlengths greater than that required to limit movement of theshutter I8 to positions in which the perforations IIa and I82L will bealigned or disaligned.

Means is provided for moving'the shutter I8 to align its perforationsI8a with the perforations Ila, vand whichV is manually operable from theexterior of the hollow body Ill. This means comprises a stem 2| turnablymounted in the body I0 atright angles to thershutter I8 and which has anend-2la projecting through the top wall I2. A cam 22 is mounted on thestem 2| and engages a cam opening I8b formed inthe shutter I8. The cam22 is eccentrically mounted upon the stem 2l so that when the stem 2| isturned through substantially 120, the shutter I8 will be moved from aposition in which the perforations IIa and Isa are disaligned to aposition in which the perforations IIa and I8a will be aligned and viceversa.

A member 45 is mounted on the shutter I8 and is for the purpose ofblocking oif certain of the perforations I8a when desired and is movableto an inoperative position. More particularly, the member 45 is in theform of a flat annular shaped par-t. It is slidably mounted on A theshutter I8 by several headed elements 46 mounted on the shutter |8 andextending through slots 4! formed in the member 45. The headed elements45 set up enough friction in conjunction with the Vmaterial of themember 45 adjacent the slots 4'! so that the member 45 is frictionallyheld in a xed position relative to the shutter I8. The member 45 isformed with a plurality of openings 45a which normally are in alignmentwith a complementary group of openings of said openings 68a formed inthe shutter I8. However, the member 45 may be moved so as not to alignthe openings 45a with the said openings lila.

Means is provided Vfor moving the member 45 relative-to the shutter I8.This means includes a pair of lingers 48 mounted on the member 45 andprojecting towards a side wall of the body I il. These lingers 43 arearranged to extend along opposite sides of the stem 2|. Another finger49 is mounted on the member 45 diametrically opposite the center pointof said lingers 48. This finger 49 is directed towards the adjacent areaof the wall of the body I. A leaf spring 59 is mounted on the side ofthe shutter I8 immediately adjacent the linger 49 and normally extendsslightly outwards of the fingers. Another spring 5I is mounted on theshutter I8 in the vicinity of the lingers 48 and normally extendsslightly outwards of the tip ends of the fingers 48.

The springs 59 and 5I act normally as stops for limiting the amplitudeof motion of the shutter I8. The stem 2| may be turned for operating thecam 22 so that the shutter I3 is moved -in one direction, for example,towards the left as illustrated in Fig. 3 until the spring 5I strikesthe side of the body I0. Then the perforations I3a and ||a are out ofalignment with each other. The stem 2| may be moved to move the cam 22in the other direction so that shutter I8 moves towards the right untilthe spring 59 strikes the body I9 and then the perforations i8a areperfectly aligned with the perforations IIa. It is possible to move thestem 2|a so that the cam 22 moves the shutter I8 to intermediatepositions so as to partially align the lperforations Ida with theperforations Ha.

The perforations 45a of the member 45 may be moved out of alignment withthe perforations Iiia by turning the stem 2| so as to cause the cam 22to move the shutter I8 towards the right, as illustrated `in Fig. 3, toan extreme position in which the spring 59 will be compressed. When thishappens the ngers 49 strike the body I0 and move the member 45 towardsthe left relative to the shutter I8. When the spring 59 is tautlycompressed the perforations 45a will be out of alignment with the saidcertain perforations |821. These perforations 45a may be moved back intoalignment by turning the stem 2| so that the cam 22 moves the shutter I8to the extreme left, as illustrated in Fig. 3. During this motion thespring 5| will be compressed so that the finger 49 strikes the body I9and the member l45 is moved towards the right in relation to the shutterI8.

Means is provided for holding the stem 2| in Xed positions forpreventing the shutter ||8 from accidentally moving except when the stem2| is manually turned. This means includes a conical ,Shaped member 23which is mounted on the stern` 2| intermediate of its ends and within anenlarged opening IIIa formed in one side of the hollow body I9. Afriction member 24 is mounted within the tcp end of the enlarged openinglea and is formed with a conical shaped opening into which the conicalshaped member 23 is adapted to be urged for frictionally maintaining thestem 2| in its adjusted positions. A spring 24 is coaxially mounted uponthe stem 2| and operatesl between the bottom wall and the opening Iiiaand the bottom face of the conical shaped member 23 for urging the stem2| upwards into a position in which the conical shaped member willengage the 'friction element 24. The bottom end of the stem 2| isrotatively and slidably supported in a bearing 25 mounted within anenlarged opening ib formed in the bottom wall II for permitting the stem2| to be manually urged inwards against the action of the spring 24 todisengage the conical shaped member 23 from the friction element 24 topermit the stem 2| to be manually turned to operate a cam 22 and adjustthe position of the shutter I8.

rllhe projected end 2|a of the stem 2| is formed with an enlarged head26 which is adapted to be manually grasped for facilitating the movementof the shaft 2| and the turning thereof for the purpose of aligning anddisaligning the perforations IIe and Ia.

The hollow body i9 is formed with a horizontal intermediate Wall 21having its edge portions 21a bent upwards and through which fasteningelements 23 are engaged for maintaining the wall 2l in position withinthe body I9. The intermediate wall 2l' is formed with an upwardly eX-tending neck opening 2lb. A container 29 containing the uid to be usedfor saturating the bristles i5 is adapted to be passed into the upperhalf ci" the hollow body I0 when the cover I is removed therefrom. Thecontainer 29 is formed with a neck 29a which is adapted to be threadedlyengaged upon the neck 2lb for permitting the liquid to pass from thecontainer 29 through the necks 2'|b and 292L and into the bottom portionof the hollow body I0.

The operation of this form of the invention is as follows: For fillingthe hollow body I9, the stem 2| is manually urged inwards and rotated tomove the shutter I3 to a position in which the perforations I|a and .I8aare disaligned. The cover IS is then removed from the opening VI2a inthe top wall I2 and the container 29 is passed into the hollow body `II]and its neck '39a threadedly engaged on the neck 2lb of the intermediatewall 2, It is necessary that the reservoir brush be inverted while thecontainer 29 is be- -ing engaged into the hollow body I9 for preventing.the liquid from spilling upon the intermediate wall 2l'.

The cover I3 is then replaced upon the top wall I2 and the vbrush isready for use. For saturating the bristles with the liquid within thehollow body the stem 2| is manually urged inwards by pressing upon thehead 25 to cause the conical shaped member 23 to be disengaged from thefriction element A24 and the stem 2| is rotated Ywhile in its depressedcondition ,for causing the cam 22 to move the shutter I8 to a positionin which the perforations IIa and Iia are aligned for permitting theliquid to vpass through the Aperforations and on to the bristles I5.After the bristles are saturated to the desired 'degree the perforationsI Ia and I3a are again disaligned by moving 'the shutter I8 in thedesired direction by using the stem '2I.

`of bristles I5.

During the initial .application of liquid to the bristles I5, it isadvisable that the perforations t5a and certain of the perforations I8be in alignment with each other. This causes the liquid to pass throughall of the perforations I8 and the aligned perforations I Ia to quicklysaturate all of the bristles I5. However, after this initial saturationit is advisable that the perforations 45a be moved out of alignment withsaid certain perforations |82. Then the discharge of the liquid will belimited to the central area This arrangement prevents too much of theliquid from reaching the outer area of bristles I5 and causing too muchdischarge of the liquid.

According to the modification of the invention shown in Fig. 5 theconstruction of the reservoir brush is similar to that previouslydescribed except that the hollow body I is not formed with theintermediate wall 21. The top wall I2 is formed with a reduced openingI2" through which the fluid may pass for filling the interior of thehollow body I0. A plug 30 is adapted to be threadedly engaged into theopening I2 and a rubber gasket 3| is mounted on the plug 30 and isadapted to be clamped between the adjacent faces of the top wall I2 andan outwardly extending flange 3Ua of the plug 30 for preventing theliquid from leaking through the top wall I 2'. In other respects thisform of the invention is similar to the previous form.

According to the modification shown in Figs. 6 and 'l the hollow bodyIII is in the form of a reservoir mop having a plurality of cords Imounted upon the bottom face of the bottom wall II for forming themopping surface thereof. An elongated handle 31 has one of its endsattached to the top face of the top wall I2 and is provided with apassage 31a which extends completely therethrough and which is connectedwith the interior of the hollow body IIJ by means of an opening 38 whichextends through the top wall I2.

From a careful inspection of Fig. 7 it will be noted that the openings31a and 38 are in end alignment with each other. The bottom end of thehandle 31 is formed with an outwardly extending fiange 31h and a rubbergasket 39 is vmounted between the adjacent faces of the bottom end ofthe handle 31 and the top face of the top wall I2 for preventing theleakage of liquid therethrough. The upper end of the handle 31 is formedwith an enlarged opening 31la which continues from the opening 3111 andto which the neck 40 of a container 4I is adapted to be engaged. Thecontainer 4I is adapted to be lled with an oil or other fluid commonlyused for saturating the cords I 5 which are mounted upon the bottom wallII.

A valve is provided in the handle 31 for controlling the passage of theliquid from the container 4I to the interior of the hollow body I0. Thisvalve is in the form of a ball 42 mounted within an enlarged portion ofthe opening 31a and which has a handle 42a extending to the exterior ofthe handle by which the ball may be turned. The ball 42 is formed with apassageway 42b which extends therethrough and which is adapted to bealigned with the passage 311ab for permitting the uid to passtherethrough. In other respects this form of the invention is similar tothe previous forms.

It is to be understood that this device may be used in homes, factories,on railways, ships,

and in connection with army and navy equipments, also for cleaning andlubricating gun barrels of all calibres.
